APPARATUS FOR DYEIN G YARNS.

SPECIFICATION forming part of Letters Patent No. 231,014, dated August 10, 1880.

Application filed May 25, 1880.

To all whom it may concern:

Be it known that I, FREADRIOK P. DANUN- BAUER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Dyeing Yarns, of which the following is a specification.

In apparatus for dyeing yarns, as heretofore constructed, the skeins or hanks of yarn have been suspended from rollers or cross bars placed above the tank containing the dyeing material, and the skeins have to be turned by hand to immerse all portions of the yarn. This operation is laborious, and requires handling of the skeins while saturated with the hot dyestuffs.

The object of my invention is to turn the skeins of yarn regularly and automatically by machinery to the extent required; and myiuvention consists,-first, in a series of nippingrollers hung on vibrating arms and fitted for movement to and from the supporting-bars of the yarn to draw the yarn around the bars a regulated distance at each vibration; second, in an automatic stop-motion for shifting the driving-belt and stopping the mechanism when the desired number of turns have been given to the skeins, so that they may be removed.

The construction and operation will be described more particularly hereinafter with reference to the accompanying drawings, wherem- Figure l is a side elevation, partially in section, of a dyeing-tank fitted with my improvements, and Fig. 2 is a sectional plan view of the same. I

Similar letters of reference indicate corresponding parts.

A is a tank of usual character for containing the dyeing liquid, and fitted at the top with the cross-bars a for supporting the skeins of yarn. These bars a are supported in open boxes at the upper ends of screws b, that are tapped into the sides of tank A, so that the bars may be adjusted vertically, and may also be lifted from their supports in applying and removing the skeins.

At one end of tank A, in suitable bearings, is fitted a cross-shaft, c, carrying fast and loose pulleys d d for a driving-belt, and carrying at its ends theieccentrics e e.

(Model.)

Upon each side of tank A, in boxesf, are fitted slide-rods ff, one at each side of the tank, upon which rods arms 9 are fixed adj usta-bly, and from the arms 9 rods h extend to and are connected to cross-heads g, that are fixed to the straps of eccentrics 0. Upon the rods f there are fixed curved standards 43, that are formed at their upper ends to receive the shafts of rollers It, so that said rollers extend across the top of the vat from the standard i at one side to the standards at the other side. Upon the standardsi angle-levers Zare pivoted, the upper ends of which extend horizontally, or nearly so, beneatlnthe rollers 7c, and are formed with open boxes for receiving the shafts of the rollers m, that also extend across and above the vat.

Upon each side of tank A is hung a cogged segment, a, the supporting-arms of which are slotted to receive the adjustable crank-pins of rod 02/, that pass to and are connected with the cross-heads 9. Above and meshing with the segments a are racks 0 0, that are suspended from links 0, that connect the lower ends of the angle-levers I. These racks o are hung to links 0 by a knuckle-jointed connection at one end, so that the outer ends of the racks are free to accommodate themselves to the curved movement of the levers l, and springs m between the racks and links serve to retain the rack in gear during such movement.

7c are slotted guides attached to the sides of the tank to prevent side movement of the segments a, and forked pieces Z, attached to the racks 0 and extending at opposite sides of links 0, prevent lateral movement of the racks. By this construction the revolution of the shaft 0 imparts a reciprocating movement to the rods f and oscillates the segments a, which movement of the segments, acting through racks 0, gives a vibratory movement to the angle-levers lat the same time they reciprocate with the standards 1'.

There is a pair of the rollers 70 m for each bar a, and the devices described being properly adjusted, said rollers 70 m first move toward their respective bars a. The rollers m then close up against rollers 70, withdraw, and

time of the opening movement may be varied and the pull on the skeins at each reciprocation regulated. The skeins are to be suspended, as shown, both by the bars a and rollers m, so that when the rollers close together they grasp the skeins, and at the backward movement draw them over the bars, thus turning the skeins and bringing all parts into the liquid.

To automatically arrest the movementwhcn the skeins have been turned a definite number of times, I use the automatically-aetingmechanism next described for shifting the belt from the fast pulley d to the loose pulley (1.

Upon a stud at one side of tank A is hung a ratehet-wheehp, and also a pawl, 17, engaging with wheel 1) to prevent back movement. The wheel 19 is provided on its outer facewith a number of apertures, arranged in a circle, to receive a screw-pin, q.

Upon tank A, adjacent to shaft 0, is hung a lever, r, the upper end of which projects in the path of a cam, r, on shaft 0. To thelower end of lever r is hung a rod, 8, that extends through suitable guides at the side of the tank, and carries at its outer end a spring finger or pawl, s, that engages with ratchetwheel 12. The cam r acts at every revolution of shaft 0 to move lever r and draw-rod s to turn the ratchet-wheel, and a coiled spring, q, on rod 8 throws the rod back after the cam has acted.

At the end of tank A is fitted a slide-rod, t, carrying the belt-shiftin g arms t, and also carrying a coiled spring,u, that tends to move the rod tand shift the belt to the loose pulley.

The rod t projects at the side of the tank against a plate on the end of a rod, 1 that is fitted in suitable guides, so that the rod t is held from being moved by the spring a, and the belt thereby retained on the fast pulley. The other end of rod 2; extends in front of the ratchet-wheelp, and has its end bent down in the path of the pin q. The coiled spring '0 on rod v retains said rod in the position just described.

The ratchet-wheel being turned a short distance at each revolution of shaft 0, the pin q is thereby brought sooner or later, according as it is placed, in contact with the bent end of rod 0;, and draws the said rod endwise, thereby releasing the belt-shifter t and allowing the spring a to force the belt to the loose pulley.

By lifting the bars a, and rollers m the skeins may be removed and others put in their place. The belt is then to be moved back to the fastpulley by the hand-lever 20, that is connected with rod t, and the latter is held by rods 1], as before.

By the use of this apparatus hand-labor is dispensed with for turning the skeins in the dyeing-liquid, the yarn is turned regularly and uniformly and to the extent required.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In apparatus for dyeing yarn, the combination, with the tank or vat and supportingbars of the skeins, of the pairs of rollers m and operating mechanism, substantially as and for the purpose set forth.

2. In apparatus for dyeing yarn, the reciprocating rods f, standards 11, rollers 70, vibratin g levers l, and rollers m, combined together and with the tank A and fixed bars a, substantially as and for the purposes set forth.

3. The racking-segments n, racks 0, and links 0, combined with tank A, the bars a, and the bent levers I, hung on the reciprocating standards '5, and the rollers L m, carried by standards t and levers I, for operation as shown and described.

4. In ap 'raratus for dyein yarns, in combination with the tank A and the reciprocating feed-rollers k m, operated by connections from the driving-shaft c, the ratchet-wheel 1), the rod 4;, fitted for movement by wheel 19, the sliding belt-shift t, the lever r, and the reciprocating rod 8, carrying pawl s, engaging the ratchet-wl1eel, substantially as and for the purposes set forth.
